On May 1, 2013, manufacturers will be required to change labels of Heparin Sodium Injection, USP and Heparin Lock Flush Solution, USP to express total drug content. This change from the existing USP requirements is intended to prevent medication errors. This change will align required labeling for heparin products with USP’s general requirements for all small-volume injectable products. Healthcare practitioners should be aware that current and revised heparin container labels may appear simultaneously in the marketplace.
